petawatt = 10^15
divided by
trillionth = 10^-12
is the same as 1000 watt/seconds. That's like 2-3 servers running for a second, probably doesn't generate all that much heat.

Like most lasers, it seems that efficiency on this thing is pitifully bad.]]>Apr 8th 2008 10:10AMhttp://www.engadget.com/2008/04/08/university-of-texas-fires-up-petawatt-laser-hercules-weeps/http://www.engadget.com/2008/04/08/university-of-texas-fires-up-petawatt-laser-hercules-weeps/
We have that burst for a tenth of a trillionth of a second... that's. 0.0000000000001 seconds.

now just counting the 0s I'm getting something like 100 watts.

That's no more than what an average Engadget readers gadget-collection consumes whilst on standby / charging.

Even if the lasers efficiency is at only 1%, the computers in said lab will probably eat up more power.

When they say that it produces more energy output than 2000 times the capacity of the US, take the energy capacity of the US for 1/10th of a trillionth of a second, and multiply that by 2000.

The energy output could power the US for 0.000000002 seconds (or something like that...)

Now, if they operated this thing continuously for a couple of seconds, then yeah, the lights in your house may blink...]]>Apr 8th 2008 10:13AM
